1. A microfluidic device for analyzing a specimen, the microfluidic device comprising:
an analytical column;
a trapping area for loading the specimen, the trapping area being connected on two sides to a first duct and a second duct respectively, both integrated in the microfluidic device;
a first integrated output connected to the second duct to discharge a portion of the specimen, once the specimen has flowed through the trapping area; and
a second integrated output connected to the analytical column;
wherein the first integrated output is connected to the first duct during a first period of time so as to load the specimen into the trapping area of the device while preventing loss of the specimen during loading of the specimen into the trapping area.
